Embodiment Construction

[0025] In each figure, elements having the same function and mode of operation are marked with the same reference numerals.

[0026] A valve 1 arranged according to the construction principle of the invention comprises a movable disconnecting body 2 connected to an axially extending actuating body 4 comprising a metal core 3 , and the movable breaking body 2 can be moved by the axially extending actuating body 4 . The parts 2, 3 and 4 together define a valve plunger 13 which is arranged within an open or closed outer valve housing 5 and which can resist by means of an induced force applied from said valve housing 5. The force of the return spring 11 moves, wherein the valve housing may include a coil structure, for example. Metal core 3 thus acts like an armature in solenoid valve 1 . Such a valve 1 is often also referred to as a solenoid valve. Here, in the exemplary embodiment, the core 3 is provided as solid metal. Materials containing only metals are also suitable.

Abstract

The method involves directly splashing a shut-off body (2) and / or a sleeve body (6) area by area against a metallic core (3), which is designed as a round cylindrical massive body. The shut-off body is secured in the sleeve body in a position in an air-sealed and unshakable manner. The core is used in an injection molding machine and molded by plastic, which forms the sleeve body that comprises the core. The sleeve body is mechanically connected with the shut-off body. The core is inserted into the sleeve body, and the shut-off body is injected into an axial open end (12) of the sleeve body. An independent claim is also included for a valve that is manufactured by the method.

Description

technical field [0001] The invention relates to a method for manufacturing a valve according to the preamble of claim 1 , wherein said valve has at least one shut-off body, wherein said shut-off body can be moved by a movable actuating body, wherein said movable The actuating body comprises a metal core which is introduced into a sleeve containing plastic during the manufacture of the valve. The invention relates to a valve according to the preamble of claim 5 and to a valve having at least one of said types valves for water-carrying household appliances. Background technique [0002] In electromagnetically switchable valves, a metallic core, for example a ferrous solid body, is generally arranged as an armature, which can be moved, for example axially, within the electromagnetic field of an outer coil by induced forces. During this process, the core is pressed into the plastic sleeve, thus allowing a shut-off body composed of elastic material to be connected to the plastic...
